MEMORANDUM **

Juan Valencia-Torres appeals his sentence after pleading guilty to illegal reentry after deportation in violation of 8 U.S.C. § 1326. He claims the district court erred by not departing downward for cultural assimilation. We dismiss for lack of jurisdiction.

DISCUSSION

Valencia-Torres agreed, as part of a negotiated plea agreement, to waive his right to appeal his sentence. Such waivers will be enforced if “knowingly and voluntarily made.” See United States v. Martinez, 143 F.3d 1266, 1271 (9th Cir. 1998). Valencia-Torres contends that his waiver was not voluntary based on statements he made at his plea hearing. We reject that contention. The record indicates that the district court carefully questioned Valencia-Torres to ensure that he understood his rights and that his waiver was both voluntary and informed. Accordingly, we lack jurisdiction to review Valencia-Torres’s sentence. See United States v. *616Vences, 169 F.3d 611, 613 (9th Cir. 1999) (noting that effective waiver of appeal deprives appellate court of jurisdiction). Moreover, we note that even if Valencia-Torres had not waived his right of appellate review, we lack jurisdiction to review the district court’s discretionary decision not to depart downward. See United States v. Tam, 240 F.3d 797, 805 (9th Cir. 2001).

DISMISSED.
